I am one of those people who compiles a lot of new kernels, and have become increasingly frustrated by the user-unfriendliness of grub2<\/strong>..<\/p>\n

Now the latest version of grub2 has introduced – for reasons that I cannot fathom – two levels of menu, and relegated most of the multiple-choice kernel version boot options to the secondary menu – euphemistically called ”Advanced options for…..<\/strong>”.<\/p>\n

The problem with this is that the conventional ways of pre-selecting the kernel version to boot are broken by this..\u00a0\u00a0 The ludicrous assumption would appear to be that the operator is sitting in front of the computer screen\/keyboard when it boots, which is not<\/span> the case when the system is remote – or ‘headless’ (or both..).<\/p>\n

There is a useful grub2 configuration tool – grub-customizer<\/strong> – that would work, but only sees the top-level menu, which usually consists of only the last-installed kernel version, and (if installed) the MSWin boot..
\nhttp:\/\/launchpad.net\/grub-customizer<\/a><\/p>\n

After much fruitless searching among the mostly-out-of-date info online, I decided to simply try to revert the menu to the older grub2 pre-2.0 single-level one, and this was actually quite easy.<\/p>\n

Simply download the source to a 1.99 version of grub2 – I used 1.99-rc1 – untar it, and go the the utils\/grub.d directory.\u00a0\u00a0\u00a0 There you will find the older version of the configuration parameter file that generates the entries for grub.cfg when grub2-mkconfig is run..\u00a0\u00a0 The file you need is 10_linux_in<\/strong>, which will need to be renamed to just 10_linux<\/strong> for Fedora systems..<\/p>\n

Copy this file to \/etc\/grub.d on your system, and make it executable (# chmod 0755 10_linux<\/strong>).\u00a0\u00a0\u00a0 Then edit the first few lines to correctly reference the exec, prefix, etc.<\/p>\n

For Fedora, this will be:<\/p>\n

 .............\n\n prefix=\"\/usr\"\n exec_prefix=\"\/usr\"\n bindir=\"\/usr\"\n libdir=\"\/usr\/share\"\n . ${libdir}\/grub\/grub-mkconfig_lib\nexport TEXTDOMAIN=grub\nexport TEXTDOMAINDIR=\"${datarootdir}\/locale\"\n\n .............<\/pre>\n
The rest of the contents should be OK as they are..<\/p>\n
Once this has been done, simply recreate grub.cfg:
\n# grub2-mkconfig -o \/boot\/grub2\/grub.cfg<\/strong><\/p>\n
Then, if you (re)run grub-customizer, you will see all<\/span> the bootable<\/em> kernel versions, and can re-sequence them as needed…<\/p>\n
